Great device, I have 2, has served me well for over a year and still kicking. It's a nice and simple semi regulated tube mod. 5 clicks on and off, 3 color LED battery indicator. Finish looks and feels fantastic, splattered paint on paint. Battery cap threading is a little course but no big deal. Being able to use 3 types of batteries is great. 21700's go almost all day with a dual coil on top, 10 to 11 hours. The finish does scratch off with abuse, falls/drops and knocking around. So it will expose the brass underneath, however it doesn't look all that bad to me. Only other thing to talk about is if you are gonna use an RDA or RTA on this thing. Build low, .1 to .2 optimally. Anything higher and this thing just kicks clouds with no taste. If you want to try mechs safely this is a pretty good start. Still love it, if it dies I'll get another or the COD version.
